Integrated Jib-Foot Crane Element Reduces Assembly Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional element-mounted cranes have a high number of mechanical and electrical interfaces, leading to complex assembly processes, increased material usage, and reliability issues due to the dispersal of functional components across multiple structural elements, which complicates manufacturing, mounting, and maintenance.
Innovation Solution
A pivot-forming crane element with a centralized framework mounting the motor-driven orienting system, hoisting winch, and dispensing winch, reducing the number of interfaces and allowing for easier assembly and maintenance by integrating all key motor sets on a single framework, with the hoisting winch above the dispensing winch, and incorporating a compact design that eliminates the need for additional pulleys and simplifies cable routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functional components are dispersed on different structural elements, then adaptability to work environment is improved, but the number of mechanical and electrical interfaces increases
Solution Approach 1:
The patent merges multiple functional components (hoisting winch, dispensing winch, and their support structures) into a single integrated jib-foot forming crane element. This consolidation reduces the number of separate mechanical and electrical interfaces while maintaining the crane's adaptability to different work environments through the modular element-mounted design.
2Adaptability or versatility
If functional components are dispersed on different structural elements, then operational flexibility is improved, but assembly time and complexity increase
Solution Approach 1:
By combining the hoisting winch, dispensing winch, and their mounting structures into a single pre-assembled jib-foot element, the patent reduces assembly time on construction sites. The integrated element is supplied as a complete unit, eliminating the need for separate assembly and connection of multiple dispersed components.
3Adaptability or versatility
If functional components are mounted on multiple structural elements, then functional distribution is improved, but the number of parts and materials increase
Solution Approach 1:
The patent combines multiple functional components into a single integrated jib-foot element, reducing the total number of parts and materials required. This consolidation eliminates redundant structural elements and mounting components that would be necessary if the same functions were distributed across multiple separate elements.
4Adaptability or versatility
If functional components are dispersed, then modular architecture is improved, but reliability decreases due to multiplication of interfaces
Solution Approach 1:
By integrating the hoisting winch, dispensing winch, and their support structures into a single manufactured unit, the patent reduces the number of interfaces and connection points. This consolidation improves reliability by eliminating potential failure points at multiple connection interfaces while maintaining the benefits of modular element-mounted crane architecture.

AI summary
A pivot-forming crane element for a rotating portion of an element-mounted crane includes a framework on which a motor-driven orienting system, a hoisting winch and a dispensing winch are mounted. The motor-driven orienting system includes a pivot mechanism about an orienting axis and at least one orienting electric motor cooperating with the pivot mechanism to make the framework pivot about the orienting axis. The hoisting winch is provided with a hoisting electric motor cooperating with a hoisting drum around which a hoisting rope is wound. The dispensing winch is provided with a dispensing electric motor cooperating with a dispensing drum around which a dispensing rope is wound.
